BACKGROUND OF THE INVENTION

The present invention relates generally to computer systems and more particularly to a computer system for creating and providing a map image of real estate values.

Currently, data indicating sale prices of homes or other real estate is available from several on-line sources. This data is typically displayed in text format, wherein each entry displays the address, sales price, sales date, etc. Although these databases provide information to potential home buyers regarding sale prices in selected areas, the textual display of such information is inefficient. Further, the textual display does not provide the observer with an indication of how sale prices vary generally across geographic areas.

SUMMARY OF THE INVENTION

The present invention provides a method and computer system for creating and displaying a map image including symbols which quickly and efficiently convey information regarding real estate values in numerous geographic locations in a selected geographic area simultaneously.

Preferably, the computer system of the present invention includes a database including a sale price for each of a plurality of real estate parcels in selected geographic areas. The computer system further includes a map program which associates each of the plurality of real estate parcels to a map image location. The computer system associates each of a plurality of symbols with a range of sales prices. Preferably each symbol includes a color and a shape. Each color is associated with a different range of sales prices. Each range is further divided in to subranges, with each shape within each color associated with one of the sub-ranges. Thus, the color of a symbol indicates the range of sales prices, while the shape further defines the sub-range of sales prices.

The computer associates one of the plurality of symbols with each of the real estate parcels based upon the sales price from the value database. Each symbol is then displayed on a map image based upon the association between the real estate parcel and the map image location.

The resulting map image of the geographic area includes the plurality of symbols displayed on the map image at locations corresponding to the real estate parcels. Each symbol indicates the sale price (within the sub-range) of the real estate parcel with which it is associated.

Since each range of real estate prices is associated with a color, an observer can quickly perceive larger variations in real estate values by observing differences in color between different geographic locations. By looking further, the observer can discriminate smaller variations in real estate values indicated by the different shapes of the symbols.

Preferably, the computer system is implemented on a network, such as the Internet. The computer system provides a user with the ability to select a geographic area. Upon selection of the geographic area, the computer system displays a map image with the symbols as described above for that area. Preferably, an advertisement associated with the selected geographic area is also displayed either alongside of the map image or in a display screen prior to the map image. The advertisement would ideally be for a realtor or mortgage broker or other service or product related to the purchase and sale of homes or other real estate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention provides a computer system 20 for creating and providing a map image according to a method of the present invention. The computer system 20 includes first CPU 22 for creating the map image in a manner which will be discussed below. The first CPU 22 includes a display 24 and input devices, such as a mouse 26 and/or keyboard 28. The first CPU 22 may be connected to a server 30 capable of operating a web site on a network, such as the Internet 32. The first CPU 22 is also connected to a color printer 34. Alternatively, the first CPU 22 may comprise the server 30.

The first CPU 22 includes a microprocessor 50 accessing computer memory 52, such as a hard drive, RAM, CD ROM, ROM, etc. The computer memory 52 stores a value database 54 and a map program 56. The value database 54 associates each of a plurality of geographic locations 58 a-c with each of a plurality of values 60 a-c, respectively. The geographic locations 58 preferably comprise street addresses, real estate parcel identification numbers, tax identification numbers, latitude/longitude or other unique identifiers for the geographic locations. Each value 60 preferably comprises a number representing a sale price of the associated geographic location 58. Alternatively, each value 60 could represent an appraised price, rental value or other value associated with the geographic location 58.

The value database 54 is available from real estate listings, such as the Multiple Listing Services, local municipalities, TransAmerica or other sources. Generally, the map program 56 associates the geographic locations 58 with coordinates 64 a-c on a digital street map image 66. There are many ways to implement the map program 56; however, suitable map programs 56 are available from Arcview with suitable databases and street map images 66 from ETAK or Geographic Data Technology. If the geographic location 58 is in the form of a street address, the map program 56 may first convert it to latitude/longitude information 62 a-c in order to associate it with the street map image 66. Other known programs can directly associate street address information to coordinates on the street map image 66.

Information stored on the server 30 is available to users via the Internet 32 utilizing a CPU 72 including a display 74 and input devices, such as a mouse 76 and/or a keyboard 78. The microprocessor 50 of the first CPU 22 is programmed with suitable software to perform the functions described herein, as are the server 30, CPU 72 and ISP 44.

The first CPU 22 is programmed to create a map image 80 shown in FIG. 2. The map image 80 includes a plurality of symbols 82 a-h displayed around a plurality of streets 84, 86 and 88 from the digital street map image 66 (FIG. 1). Each of the symbols 82 is associated with a sub-range of values. The location of the symbol 82 on the map image 80 corresponds to a geographic location. The symbol 82 displayed indicates the value of the geographic location at which the symbol 82 is displayed. A legend 90 is preferably displayed adjacent the map image 80. As can be seen in FIG. 2, the symbols 82 include a plurality of shapes, each displayed in one of a plurality of colors. Although only four shapes and two colors are shown in FIG. 2, preferably at least eight shapes and at least five colors are utilized. Colors and shapes could be constant across all geographic areas or alternatively, colors and shapes could be assigned to ranges and subranges based upon the range of values in the geographic area. The size of each range and subrange could also vary based upon the values in the geographic area displayed. One of reasonable skill in the art and familiar with computers could select appropriate colors.

Each color is associated with a range of values. For example, in FIG. 2, the white symbols 82 a-d are associated with values between $170,001 to $210,000 and the black symbols 82 e-h are associated with the values of $210,001 and above. Within each color, the ranges of value are broken into sub-ranges, each associated with a shape. For example, the white circle symbol 82 a is associated with values between $170,001 to $180,000, the white square symbol 82 b is associated with values from $180,001 to $190,000 and so on as shown in the legend 90 of FIG. 2.

Thus, an observer of the map image 80 of FIG. 2 quickly and efficiently ascertains general trends in values based upon colors in certain areas on the map image 80, which includes a certain geographic area. After discerning general trends (if any) between geographic location and values, a user can discern values more specifically, i.e., into the sub-ranges, by observing the specific shapes of the symbols 82 within each color.

It should be noted that the map image 80 (and legend 90) could be displayed on a computer display, such as the computer displays 24, 74 of FIG. 1 or printed on paper, such as by the printer 34 of FIG. 1. If the map image 80 is displayed on a computer display, a user could select additional information about any of the geographic locations associated with a symbol 82. For example, by moving a cursor 96 over the symbol 82 b, a pop-up display 98 appears adjacent the symbol 82 b, indicating additional information regarding the geographic location associated with symbol 82 b, such as street address, exact value and/or date of the sale. Although a very small geographic area is shown in map image 80 of FIG. 2, preferably, the user can selectively change the scale of the map image 80 and select different geographic areas in a manner similar to known computer map display programs.

The map image 80 of FIG. 2 is created by the first CPU 22 of FIG. 1. The method of creating the map image 80 of the present invention will be described with respect to FIGS. 1 and 2. The first CPU 22 associates each of the plurality of symbols 82 a-h with a sub-range of values, associating each color with a range and each shape within each color with a sub-range, generally as shown in the legend 90 of FIG. 2.

Although each of the sub-ranges could be equal, the sub-ranges of the symbols at the higher value colors are preferably larger. As shown in FIG. 2, the symbols 82 a-d for a first color each cover a $5,000 sub-range, while the symbols 82 e-j for a second color each cover a $10,000 sub-range. Additionally, or alternatively, there could be a greater number of symbols for the higher value colors than the lower value colors. As shown in FIG. 2, the second color (range) includes more symbols 82 e-82 j than the first color (range). Again, the number of symbols or the size of the sub-ranges can each be varied, or both.

The CPU 22 then reads the value database 54 and associates one of the plurality of symbols 82 with each street address 58 in the value database 54. Each symbol 82 may be used for more than one coordinate 64, as more than one real estate parcel falls within the associated sub-range. The map program 56 and the CPU 22 then convert or correlate the street addresses 58 to latitude/longitude information 62. The latitude/longitude information 62 is then converted or correlated to coordinates 64 on the computer street image 66. Alternatively, the CPU 22 and map program 56 may directly convert or correlate the street addresses 58 to the coordinates 64. Alternatively, the geographic locations 58 may be latitude/longitude information 62.

Thus, street address 58 a is associated with value 60 a, latitude/longitude information 62 a and coordinate 64 a. Likewise, street address 58 b, value 60 b, latitude/longitude information 62 b and coordinates 64 b are also associated, and so on. The CPU 22 then generates the map image 80, displaying the street image 66 with the symbols 82 displayed at their associated coordinates 64 on the street image 66, as shown in FIG. 2.

For example, street address 58 a (“123 Oak”) is associated with a value 60 a of $186,000. Thus, CPU 22 associates symbol 82 b ($180,001-190,000) with street address 58 a. CPU 22 also determines that symbol 82 b should be displayed at coordinates x_(a),y_(b). This is demonstrated in FIGS. 1 and 2. Coordinates x_(a),y_(b) on street image 66 correspond to the proper geographic location on the map image 80 relative to the streets 84, 86, 88.

When a user accesses the server 30 of Internet 32, the user of CPU 72 is first presented with one or more geographic area selection screens, such as shown in FIG. 3, on display 74. The geographic area selection screen displays a plurality of geographic areas 100 a-c, each associated with a map image, including map image 80 of FIG. 2. Upon selection of a geographic area 100 from the display in FIG. 3, an advertisement screen 102, such as that shown in FIG. 4, is preferably displayed on the user's display 74. The advertisement screen 102 includes an ad 104 and/or Internet link 106. Preferably, the ad 104 and/or link 106 is for a product and/or service related to the associated geographic area 100 (FIG. 3). Most preferably, the ad 104 and/or link 106 is also related to the purchase, sale or ownership of real estate, such as realtors, mortgage brokers, etc. The ad screen also includes a link 108 to the map image screen shown in FIG. 2. Alternatively, the user could enter a starting address on the user's CPU 22 to select a geographic area in a manner similar to known computer map and driving instruction programs.
